I plan to present a slideshow (with audio track) from my MacBook Pro to an HDTV with a direct HDMI connection. However, I am not having any luck trying to figure out a way to play the audio track through the HDTV' speakers rather than through the MacBook Pro. Is this possible to do?

Based upon my limited knowledge, my preference would be to run the audio through the DVI-HDMI cable for better sound fidelity; hence, my question.

What I discovered is that my Mac is too old to support audio through the DVI-HDMI cable. So for the time being, I simply connected the headphone jack on the Mac to a couple of audio input ports on the back of the HDTV. After a quick configuration, all is fineThank you.
